This paper introduces physics-based stripline ports for a segmented optimization of component footprints on printed circuit boards (PCBs). A segmentation is used for dividing a digital communication system into well-defined parts that are considered to be mostly independent. This technique is widely used in conjunction with generic 3-D electromagnetic field solvers, but it is new to physics-based...
This paper presents initial results on spurious trace-via interactions, i.e. the coupling between striplines and vias that are routed in close proximity in printed circuit boards. It is shown that the primary interaction is mediated by a capacitive coupling. Moreover, antipads of signal vias act as discontinuities in the return current path of striplines. The relevance of this effect is increased...
